Abstract
OBJECTIVE The set of exposures to chemical substances and their role as a cause of disease gives rise to the concept of the exposome, partially made up of chemical pollutants to which an individual is exposed, which is why, unlike the genome, it is an a priori modifiable factor, its study being crucial in terms of Public Health. The population of the Canary Islands has been studied in terms of its levels of chemical contamination, with numerous biomonitoring studies, which makes it necessary to characterise its exposome and its consequences in terms of disease, in order to implement specific corrective measures to minimize the impact on its health. METHODS A review of scientific literature (MEDLINE and Scopus) was made, according to PRISMA criteria and PICO methodology, to include studies on biomonitoring of pollutants, or evaluating the effect of pollutants on diseases prevalent in the archipelago. RESULTS Twenty-five studies, both population-based and hospital-based, were selected. The results show that the exposome is made up of at least 110 compounds or elements, 99 of which appear to be present from the intrauterine stage. The presence of chlorinated pollutants and metals stands out, which seems to be related to the high incidence of metabolic diseases (diabetes), cardiovascular diseases (hypertension) and certain types of neoplasms (breast cancer). In short, the consequences are conditioned by the genome of the exposed population, reinforcing the enormous importance of genome-exposome interactions in the development of pathologies. CONCLUSIONS Our results indicate that it is necessary to establish corrective measures on the sources of pollution that modify the exposome of this population.

Abstract
Despite the Mediterranean Sea being one of the world's marine biodiversity hotspots, it is a hotspot of various environmental pollutants. This sea holds eight cetacean with resident populations whose numbers are considered to decline in the last decades and which are particularly susceptible to POPs bioaccumulation due to their peculiar characteristics. In this work, we studied blubber concentration of various OCPs and several PCBs and PBDEs congeners in cetaceans stranded in the northern coast of the Gulf of Vera (Region of Murcia, SE Spain) between 2011 and 2018. Most compounds and congeners were above the limit of detection in most samples, although some pesticides like endosulfan stereoisomers or endrin were never detected. DDT and its metabolites, PCBs and metoxychlor appear as the dominant compounds while PBDEs shows concentrations of lower magnitude. Striped dolphin was the species accounting for higher concentrations of most pollutants. There were differences in concentrations and profiles between species which could be partially explained by differences on diet and feeding behavior. We also observed differences based on life history parameters suggesting maternal transfer for most POPs, in accordance with other works. DDE/ ΣDDT ratio suggest no recent exposure to these pesticides. Despite showing lower concentrations than some previous works, PCB concentrations accounted for higher total TEQ than many studies. According to toxicity thresholds in the literature, we cannot guarantee the absence of health consequences on populations studied, especially for those caused by PCBs. These findings are of major importance considering the relevance of the study area in the conservation of Mediterranean cetaceans.

Abstract
The biomagnification and biodilution of inorganic pollutants, have a close correlation on the structure and function of trophic change behavior; sea turtles represent an excellent bioindicator model to identify their impact in marine ecosystems. To understand pollution effects on marine ecosystems, we quantified the bioconcentration of 50 inorganic elements in the blood and scute tissues of three nesting species of sea turtles (Chelonia mydas, Eretmochelys imbricata and Caretta caretta), collected in Quintana Roo State from July 2017 to August 2018. As a general trend, essential mineral elements with toxic potential showed the highest concentrations in both tissues; significant increase concentration of arsenic, mercury, and cerium levels was observed with increasing trophic levels indicating its biomagnification while a significant decrease in manganese and bismuth showed a biodilution effect. We expect that our findings can be used as baseline data in future biomonitoring and contamination risk assessment programs in the region.

Abstract
Plastic pollution constitutes an environmental problem in the Canary Islands nowadays. Nevertheless, studies evaluating the impact of plastics on its avifauna are still scarce. Gastrointestinal tracts of 88 birds belonging to 14 species were studied for the presence of plastics. Moreover, their livers were analyzed for the determination of bromodiphenyl ethers (BDEs), polychlorinated biphenyls (PCBs), polycyclic aromatic hydrocarbons (PAHs) and organochlorine pesticides (OCPs). Among Cory's shearwaters (n = 45), the frequency of occurrence of plastic ingestion was considerably high (88.89 %). This species had the highest mean value of items (7.22 ± 5.66) and most of them were compatible with lines derived from fishing gear. PCBs and PAHs were detected in all of the samples and OCPs in the great majority of them (98.86 %). Our results highlight the problems that plastic debris (mainly for seabirds) and organic pollutants pose to these species.

Abstract
The number of craft breweries and the volume of craft beer produced globally is growing exponentially. However, little is known about their differences with mainstream beers regarding mycotoxin profile, pesticide and pollutant residues and elemental composition. Given that beer is one of the most consumed beverages worldwide, it is important to shed light on its toxicological profile. In this study, samples of 23 craft beers and 19 mainstream Spanish beers were collected to perform a comparative analysis including 8 mycotoxins, 225 pesticide residues and 50 POPs, and 50 elements. Mycotoxins were not detected in craft beers, while 100% of mainstream beers presented at least one mycotoxin. In contrast, craft beers contained higher average pesticide residues than their mainstream counterparts, although significant differences were only found in Mepiquat and Metrafenone content. No persistent organic pollutants were detected in any sample. The elemental composition presented differences between the two groups both in the concentration of elements and their hierarchy. In conclusion, the toxicological profile of all beers was safe and is unlikely to constitute a hazard to consumer health. Craft beers present significant differences from their mainstream counterparts in all the dimensions explored.

Abstract
Marine microplastic pollution is one of the biggest environmental problems we face. The growth of plastic production has not ceased since the 1950s and it is currently estimated that 368 tons of plastic were produced in 2019 (PlascticsEurope, 2020). Geyer et al. (2017) estimate that 79% of the plastic produced in the world still remains in the environment; this plastic due to the effect of degradation and subsequent fragmentation, is present in the form of microplastics in all oceans and, due to its small size can be ingested by fish and filter-feeding organisms. In addition, microplastics have additives and chemical contaminants associated with them, and the potential effect of microplastic ingestion on marine organisms, and through them, the potential risk to humans, is unknown. In the present study, European seabass (Dicentrarchus labrax) were fed for 60 days with three treatments: Control (feed), MP (feed with 10% virgin microplastics) and EMP (feed with 10% environmental microplastics), being the first study to evaluate long-term accumulation of contaminants due to ingestion of environmental microplastics (EMP) in fish. Both plastic additives such as PBDEs, and chemical contaminants adsorbed from the environment such as PCBs and DDE, were analyzed in the EMP, feed and liver. The concentration of microplastics in the feed was calculated based on the MPs/zooplankton wet weight (WW) ratio of 0.1 found in an area of maximum accumulation in the Canary Islands. Therefore, it is an experiment that simulates real conditions, but in the worst-case scenario, using both, concentrations based on data obtained in oceanographic campaigns and microplastics collected from the environment. Our results show that in this scenario, additives and chemical contaminants adsorbed on EMPs bioaccumulate in fish liver due to long-term ingestion of microplastics.

Abstract
The organic wine market is rapidly growing worldwide, both in terms of production and consumption. However, the scientific literature is not conclusive regarding differences in the elemental composition of wines according to their production method, including both major and trace elements. Minerals can be present in wine as a result of both anthropogenic and environmental factors. To date, this has not been evaluated in volcanic contexts, neither has the emergent issue of rare earths and other minority elements as potential sources of food contamination. This study using inductively coupled plasma mass spectrometry (ICP-MS) analyses organic and conventional wines produced in the Canary Islands (Spain), an archipelago of volcanic origin, to compare their content of 49 elements, including rare earths and minority elements. Our results showed that organic wines presented lower potential toxic element content on average than their conventional counterparts, but differences were not significant. Geographical origin of the wine samples (island) was the only significant variable differentiating wine samples by their composition profiles. By comparing our data with the literature, no agreement was found in terms of differences between organic and conventionally-produced wines. This confirms that other factors prevail over elemental composition when considering differences between wine production methods. Regarding the toxicological profile of the wines, five samples (three organic and two conventional) exceeded the maximum limits established by international legislation. This highlights the need for stricter analytical monitoring in the Canary Islands, with a particular focus on Cu and Ni concentration, and potentially in other volcanic areas.

Abstract
The major purpose of human biomonitoring is the mapping and assessment of human exposure to chemicals. The European initiative HBM4EU has prioritized seven substance groups and two metals relevant for human exposure: Phthalates and substitutes (1,2-cyclohexane dicarboxylic acid diisononyl ester, DINCH), bisphenols, per- and polyfluoroalkyl substances (PFASs), halogenated and organophosphorous flame retardants (HFRs and OPFRs), polycyclic aromatic hydrocarbons (PAHs), arylamines, cadmium and chromium. As a first step towards comparable European-wide data, the most suitable biomarkers, human matrices and analytical methods for each substance group or metal were selected from the scientific literature, based on a set of selection criteria. The biomarkers included parent compounds of PFASs and HFRs in serum, of bisphenols and arylamines in urine, metabolites of phthalates, DINCH, OPFRs and PAHs in urine as well as metals in blood and urine, with a preference to measure Cr in erythrocytes representing Cr (VI) exposure. High performance liquid chromatography-tandem mass spectrometry (LC-MS/MS) was the method of choice for bisphenols, PFASs, the HFR hexabromocyclododecane (HBCDD), phenolic HFRs as well as the metabolites of phthalates, DINCH, OPFRs and PAHs in urine. Gas chromatographic (GC) methods were selected for the remaining compounds, e.g. GC-low resolution MS with electron capture negative ionization (ECNI) for HFRs. Both GC-MS and LC-MS/MS were suitable for arylamines. New developments towards increased applications of GC-MS/MS may offer alternatives to GC-MS or LC-MS/MS approaches, e.g. for bisphenols. The metals were best determined by inductively coupled plasma (ICP)-MS, with the particular challenge of avoiding interferences in the Cd determination in urine. The evaluation process revealed research needs towards higher sensitivity and non-invasive sampling as well as a need for more stringent quality assurance/quality control applications and assessments.

Abstract
The population of the Canary Islands has been exposed to high levels of persistent organic pollutants (POPs). Biomonitoring studies are essential to know the temporal trend in residue levels, particularly of substances banned decades ago. The purpose of this study was to analyze the distribution of plasma concentrations of 59 POPs in 175 participants from the PREDIMED-Plus trial (2014-2016), and to compare them with the distribution of these POPs in 343 participants in the PREDIMED trial (2006-2009). All participants had metabolic syndrome. No difference in the distribution of age, gender or BMI was observed between trials. POPs were determined by gas chromatography-mass spectrometry. Density plots -POP Geoffrey Rose curves- were used to represent the full population distribution of each compound. Three out of 59 POPs were detected and quantified in ≥95% of the samples (p,p'-DDE, median = 694.7 ng/g lipid; HCB, median = 57.0 ng/g lipid; and β-HCH, median = 75.7 ng/g lipid). PCB congeners 138, 153 and 180 were detected in 64.6, 40.0 and 88.0% of the samples. Females showed highest concentrations of organochlorine pesticides and those subjects who lost ˃ 5 kg showed significant higher plasma concentrations of POPs. In a range of 6-14 years, plasma concentrations of POPs decreased 3.3-21.6 fold, being notable the decrease of 28.7-fold observed for HCB among women. Despite this sharp decline, levels of POPs are still higher than those reported in other regions, since one third of the subjects included in the present report had high concentration of more than three pollutants. Continuous biomonitoring studies are required to know the evolution of the levels of residues and to evaluate the effectiveness of environmental policies.

Abstract
Heavy metals and other toxic elements are frequently detected in humans. Rare earth elements (REE) have arisen as a novel group of substances considered as emerging pollutants due to its dependence for high tech industry. We designed a study aimed to conduct the biomonitoring a total of 45 inorganic elements in the population of Andalusia (Spain). A total of 419 participants were recruited and their plasma samples analyzed. Concentration of elements, including elements in the ATSDR's priority pollutant list and REE were measured by ICP-MS in the blood plasma of participants. Arsenic, copper, lead, selenium, antimony, strontium, and bismuth were detected in ˃98% of subjects. Median values of arsenic, mercury and lead were 1.49, 1.46, and 5.86 ng/mL, respectively. These concentrations did not exceed reference values published by international agencies. We observed a positive correlation between age and plasma concentrations of arsenic, mercury, antimony and strontium. Sum of elements was lower in the group of subjects younger than 45 years old (P = 0.002). Positive correlations were observed between body mass index (BMI) and plasma concentrations of barium, cerium, osmium, tin, and ytterbium. 7 out of 26 REEs showed a percentage of detection ≥ 90%. Bismuth, yttrium, and cerium were quantified at the highest concentrations (median value = 7.7, 0.19, and 0.16 ng/mL, respectively). We found that plasma levels of 6 REEs were higher among males, and a positive correlation between REEs and age was detected. The present results suggest a potential interaction with the human physiology that deserves additional research. Given the high persistence of these elements in the environment, and the significant technological dependence on them, future studies are needed to elucidate the potential sources of exposure and possible adverse effects on health, especially in the most vulnerable populations.

Abstract
BACKGROUND Methylchloroisothiazolinone (MCI) and methylisothiazolinone (MI) contact dermatitis is a severe problem. The high concentrations of these substances and other isothiazolinones such as benzisothiazolinone (BIT) and octylisothiazolinone (OIT) contained in cleaning products may cause allergic contact dermatitis in sensitized patients. OBJECTIVES To evaluate the exposure to isothiazolinones contained in cleaning products on the market and from sensitized patients, and to verify the accuracy of labeling. METHODS A total of 34 cleaning products were collected (17 supplied by sensitized patients and 17 bought randomly). Analysis was made of the concentrations of MI, MCI, BIT, and OIT using liquid chromatography tandem mass spectrometry (LC-MS/MS). RESULTS MI and BIT were the components most frequently detected. Of all the products analyzed, 76.5% contained at least one isothiazolinone. Twelve products had an MI concentration above the permitted level for rinse-off cosmetics. Most of them were coming into direct contact with the skin in daily use. Mislabeling occurred in eight products. CONCLUSIONS Some cleaning products with high concentrations of isothiazolinones may cause cutaneous symptoms in sensitized patients, especially in spray form. The labeling should be correct, also regarding the use of each article.

Abstract
The aim of this study was to analyze the prevalence of ethanol in individuals (277) subjected to a mandatory medico-legal autopsy in the Institute of Legal Medicine of Las Palmas (Canary Islands, Spain) during 2016-2017, comparing the results with data published in 2015. Blood and/or vitreous humor samples were analyzed by gas chromatography. 31.8% of the individuals were positive to ethanol. We observed a decrease in the prevalence of ethanol among males (p = 0.002). While the prevalence of ethanol was reduced, the concentration among those positive subjects has increased. 11.9% of the series died in a traffic accident and the percentage of positive to ethanol decreased in relation to 2015 (64.3, 25.0, and 35.3%). The number of suicides remains constant, although the age of the suiciders has been significantly reduced (p = 0.022). The results of this study indicate that ethanol is still heavily involved in non-natural deaths.

Abstract
A large number of nesting loggerhead sea turtles (n = 201) were sampled to establish the blood levels of 11 elements (Cu, Mn, Pb, Zn, Cd, Ni, Cr, As, Al, Hg, and Se). Almost all of the samples showed detectable levels of these 11 elements, and Zn and Se exhibited the highest concentrations (median values as high as 6.05 and 2.28 μg/g, respectively). The median concentrations of the most toxic compounds, As, Cd, Pb, and Hg, were relatively low (0.38, 0.24, 0.06, and 0.03 μg/g, respectively). We also determined the haematological and biochemical parameters in a subsample of 50 turtles to evaluate the potential effects of these contaminants on clinical parameters and found several associations. Our study reinforces the usefulness of blood for the monitoring of the levels of contaminating elements and their adverse effects on blood parameters in sea turtles.

Abstract
We describe the morphologic and toxicological findings in a case of pansteatitis in a stranded loggerhead sea turtle Caretta caretta. At necropsy, a large amount of adipose tissue in the celomic cavity showing very firm, yellow to orange irregular formations was observed. Histological lesions ranged from the infiltration of necrotic fat by scarce multinucleated giant cells and numerous macrophages containing xylene-insoluble lipopigment inclusions to the presence of several granulomas characterized by an irregular central necrotic area consisting of lipopigment surrounded by numerous multinucleated giant cells. Microbiological cultures were negative. Celomic fat was analyzed for PCBs and DDTs, resulting in very high levels of PCB 138, 153, 180 209 (3170, 2830, 980 and 1190 ng g-1, respectively). Although a nutritional cause cannot be ruled out, the high levels of PCBs detected in the celomic fat could have induced lipid peroxidation in adipocytes, resulting in cell damage, deposition of ceroid pigment and inflammatory response. This is the first report of pansteatitis in a wild sea turtle.

Abstract
The population of the Spanish archipelago of the Canary Islands has been studied in depth regarding its levels of contamination by organochlorine pesticides (OCs) and polychlorinated biphenyls (PCBs). Foodstuffs of animal origin, such as milk, are prominent contributors to the body burden of these contaminants. As this population presents one of the highest milk-intake in Spain and Europe, we evaluated the level of OCs and PCBs in 26 commercially available brands of milk (16 conventional and 10 organic brands) present in the market of these Islands, in order to estimate the relevance of milk as a source of these chemicals for the Canary population. Our findings showed that hexachlorobenzene, trans-chlordane, and PCB153 were present in almost all the samples with independence of the type of milk. For both types of milks, the concentration of OCs was very low, showing organic milks lower levels than conventional ones. As a consequence, the estimated daily intake for OCs was lower than the tolerable daily intake (TDI) established by International Agencies. The levels of PCBs in milk were also found to be very low, but, in this case, the situation was the opposite: there were higher levels of PCBs in organic than in conventional brands of milk. Unexpectedly, levels of dioxin-like PCBs (DL-PCBs) reached values higher than 25 pg WHO-TEQ g(-1) fat in percentile 75 for both types of milk indicating the existence of a number of brands of milk highly contaminated by these toxicants. Consequently, the population who consume the most contaminated milk brands could have estimated daily intakes well above the recommended TDI (2 pg WHO-TEQ kg(-1)b.w.d(-1)) established by European Union Authorities. These results are of concern if we consider the well known adverse health effects exerted by dioxin-like compounds.

Abstract
Our multigenerational study evaluates the hepatic effects of the xenoestrogens nonylphenol (NP), and 4-octylphenol (4OP) on male and female rats when they are exposed uninterruptedly, from conception to adult age, to tap water containing 25ppm of NP or 4OP. Our results showed that these compounds did not induce any change in liver/body weight ratio (relative liver weight, RLW). In the morphological analysis we did not find evident signs of cytotoxicity. The most relevant findings were the presence of both an increase in the apoptotic index and in the percentage of binuclear hepatocytes in livers from exposed animals. Additionally, our study revealed the presence of hepatocellular glycogenosis (mainly in 4OP-exposed rats): the type of glycogen accumulated was in aggregates (gamma-glycogen), a non-functional form of glycogen. This study demonstrates that, at levels close to those described in the environment, NP and 4OP are capable of inducing a number of hepatic effects, potentially related with adaptive, and/or metabolic alterations of liver tissue.

Abstract
Organochlorine pesticides are a lipophilic class of chemicals that persist in the environment and tend to accumulate in human tissues for years. They came into widespread use in the late 1940s. Because of their capacity to bioaccumulate and biomagnify in food chains and their toxic effects, most of them were banned in industrialized countries, among them Spain, in the late 1970s and 1980s. In 1998 organochlorine pesticides were determined in a representative sample of a Spanish population (around 690 serum samples from people 6 to 75years old from the Canary Islands). Serum levels of lindane aldrin, dieldrin and endrin, were determined. Our results showed that a high percentage of samples presented detectable levels of some of the organochlorines measured, endrin being the most frequently detected (72%) and at highest concentration (mean 136.7ng/g fat). Mean concentrations of the main cyclodiene evaluated, dieldrin, was lower to those found in other Western populations. However, serum levels of lindane were higher than those described in North European populations. Influence of geographical and sociodemographic factors was evaluated. Urban populations showed the highest levels of dieldrin, while non-urban population showed the highest serum values of lindane, aldrin and endrin. Unexpectedly, serum values of lindane, aldrin and dieldrin were higher in younger than in older people. Subjects under 18years showed almost twice as high serum levels of lindane, aldrin and dieldrin than subjects of 65-75years. These results may well suggest that people living in the Canary Islands have been and are currently exposed to non-DDT-organochlorine pesticides. The type and source of exposure could vary between islands and type of habitat. Contaminated food and/or the environment could be related with this situation.

In this study we solubilized the male rat liver ST-binding protein (STBP) and investigated the following parameters: 1) pharmacological properties, 2) hydrodynamic properties, 3) peptidic composition, 4) the effects of age and hypophysectomy, and 5) inducibility by 17alpha-ethinyl estradiol. We found that STBP is an integral protein bound to the endoplasmic reticulum. 3-[(3-cholamidopropyl)dimethylammonio]-1-propanesulfonate (CHAPS) provided its optimal solubilization without changes in its pharmacological properties, i.e. high specificity for ST and danazol, between natural steroids and ligands of low affinity glucocorticoid-binding sites or of progesterone-binding sites. Hydrodynamic properties of the STBP showed that it has a molecular mass of at least 118 kDa. SDS-PAGE of covalently labeled STBP under nonreducing conditions showed that [3H]ST binds to a 110-kDa protein. The STBP was resolved under reducing conditions into three peptides of 55, 31, and 22 kDa, respectively. STBP increased from immature to adult rats, and it dramatically decreased after hypophysectomy. Unlike the 22-kDa peptide, both the 55- and 31-kDa peptides drastically decreased in both immature and hypophysectomized rats. 17alpha-Ethinyl estradiol administration to immature or hypophysectomized rats induced the 55- and 31-kDa [3H]STBP to a greater extent than the 22-kDa peptide. Thus, STBP appears as an oligomeric protein composed of hormone-regulated peptides. The availability of solubilized STBP and the fact that it can be induced in vivo represent major steps toward the purification and functional significance of this unique steroid-binding protein.

Abstract
Stanozolol (ST) is a 17alpha-alkyl anabolic-androgenic steroid (17alpha-AAS) often misused by athletes and bodybuilders. The use of anabolic-steroids by sportsmen and teenagers has increased dramatically, thus raising the question about their hepatotoxicity, specially those such as ST which are orally administered. Previously, we have reported diverse in vivo effects exerted by this steroid and published the existence of a highly specific ST-binding site in male rat liver microsomes. The existence of this binding site, the reported hepatic effects exerted in humans, and the very limited information about its potential hepatotoxicity led us to treat adult male rats acutely and chronically with ST and study different parameters that could indicate liver damage: serum levels of transaminases, concentration of monooxygenase enzymes in liver, liver membrane lipid peroxidation products, liver histopathology, and cell cycle/ploidy status of liver cells. In our study, no changes in serum transaminases or lipid peroxidation levels were obtained. However, acute stanozolol treatment significantly decreased the levels of cytochrome P450 (Cyt. P450) and cytochrome b5 (Cyt. b5) during the first 48 h of treatment, while subsequently, at 72 and 96 h, these microsomal enzymes underwent a significant increase in their levels. In sharp contrast with this response to acute treatment, the content of these two enzymes during chronic treatment showed an important decrease. Interestingly, acutely and chronically ST-treated livers showed slight to moderate inflammatory or degenerative lesions in centrilobular hepatocytes. Flow cytometric analysis demonstrated that both acute and chronic ST treatment were capable of increasing the percentage of S-phase fraction (%SPF) of liver cells. These findings taken together clearly show that this steroid is capable of altering the liver capacity for metabolizing xenobiotics and indicate that high doses of ST could exert a proliferative effect on liver cells. Such data should be considered in risk evaluations for this compound.

Abstract
Male rat liver microsomes contain a [3H]dexamethasone binding site, capable of binding glucocorticoids and progesterone. We have shown previously that the 17 alpha-alkylated androgen, stanozolol, can inhibit the [3H]dexamethasone binding to microsomes through a negative allosteric mechanism, which gives rise to the possibility of its interaction with a different binding site. In this study, the existence of a single-saturating binding site, capable of binding the radioactive steroid with a maximum number of the specific binding site of 49 +/- 2 pmol/mg of protein and a Kd of 37 +/- 1.3 nM was demonstrated by using [3H]stanozolol. In competition experiments, only stanozolol and danazol were able to compete with [3H]stanozolol for its binding to microsomes, among more than 60 steroids and other compounds tested. The binding of [3H]stanozolol was depressed after protease treatment of the microsomes, or after the administration of cycloheximide to adult male rats for 24 hr, which suggest its proteic nature. The [3H]stanozolol binding site was detected in many tissues of the rat, with the highest concentrations being found in the liver. It was detected from birth, increasing afterward in concentration and reaching a peak at 2 to 3 months of age. This is the first experimental verification of the existence in liver microsomes of a specific binding site for some 17 alpha-alkylate androgens, such as stanozolol and danazol, different from the androgen receptor or the [3H]dexamethasone binding site.

Abstract
Rat liver microsomes contain a single class of steroid binding sites, capable of binding various glucocorticoids and progesterone. In a previous article, we have described the in vitro interaction of several androgens with this binding site. Unlike natural androgens, the 17 alpha-alkyl derivatives stanozolol and danazol were capable of interacting with this binding site through a negative allosteric pattern. Now, the effects these steroids exert on the microsomal [3H]dexamethasone binding site have been studied in vivo. The administration of a single dose of stanozolol to rats provoked a significant reduction in the microsomal [3H]dexamethasone binding capacity. This effect was maximal two hr after stanozolol administration and persisted for six hr. The restoration of the [3H]dexamethasone binding level after stanozolol administration was dependent on protein synthesis, since it was blocked by the concomitant administration of cycloheximide. None of the other androgens tested (danazol, methyltestosterone, fluoxymesterone, and testosterone propionate) was capable of provoking a similar effect when administered 2 or 24 hr prior to sacrifice. In rats treated for seven days with a daily dose of diverse androgens and sacrificed 24 hr after the last treatment, none of the 17 alpha-alkyl androgens assayed provoked significant changes in the microsomal [3H]dexamethasone binding level, although stanozolol, danazol, and methyltestosterone provoked a significant increase in glucocorticoid receptor concentration. In contrast, the administration of testosterone propionate provoked a 50% reduction in the [3H]dexamethasone binding level without causing changes in the glucocorticoid receptor concentration. These results provide new evidence on the existence of different effects on the liver of 17 alpha-alkyl androgens, compared to the effects produced by natural androgens.

Abstract
The present work focuses on the interaction of 17 alpha-ethinyl estrogen derivatives with the [3H]dexamethasone ([3H]DEX) binding site from male rat liver microsomes and the induction of this site by the in vivo administration of natural and synthetic estrogens. [3H]DEX binds to a single-saturating binding site (Kd = 100 nM; maximal binding = 13 pmol/mg of protein) in the liver microsomes. In competition experiments, ethinylestradiol (EE2) and mestranol were able to inhibit [3H]DEX binding to microsomes, whereas natural estrogens, tamoxifen or estrogen sulfates were ineffective. Saturation analysis performed by incubating [3H]EE2 with liver microsomes revealed the existence of a low-affinity (Kd = 280 +/- 30 nM) and high capacity (maximal binding = 16 +/- 2 pmol/mg of protein) binding site. Saturation, competition and dissociation experiments suggest that [3H]DEX and [3H]EE2 interact with the same microsomal entity. Synthetic and natural estrogens increased the hepatic expression of the [3H]DEX binding site in immature, hypothyroid and hypophysectomized male rats. This induction required at least 2 days of treatment, and could only be achieved by pharmacological doses of estrogens.(ABSTRACT TRUNCATED AT 250 WORDS)
